Model Kate Upton followed through on a promise to reveal details about her allegation of sexual misconduct against Guess co-founder Paul Marciano, saying the fashion executive repeatedly groped her and called her a “fat pig” after she rejected him.

“Paul Marciano said he wanted to meet with me,” she told the magazine. “As soon as I walked in with photographer Yu Tsai, Paul came straight up to me, forcibly grabbed my breasts and started feeling them — playing with them actually. After I pushed him away, he said, ‘I’m making sure they’re real.’”

Marciano kept up his aggression, she said, “grabbing my thighs, my arms to pull me closer, my shoulders to pull me closer, my neck, my breasts, and smelling me.” Even the presence of the photographer did not discourage him, she said.

Marciano called the allegation “absolutely false.” “I have never been alone with Kate Upton,” he said in a statement emailed to HuffPost on Thursday. “I have never touched her inappropriately. Nor would I ever refer to a Guess model in such a derogatory manner.”

Upton, in the interview with Time, went on to describe a tense relationship with Marciano. She said she sometimes used photographers as a buffer to his advances, and found strategies to avoid being alone with the executive.

“It was an emotional and nonstop battle of games, power struggles and creative avoidance tactics,” the model said.
